Patients with multiple ligament reconstruction, total meniscectomy, contralateral knee surgery before ACL reconstruction, open growth plate, and less than 10\u2010year follow\u2010up were excluded in the study. The medial and lateral PTS were measured from preoperative magnetic resonance imaging. Based on Li et\u00a0al.\u2019s previous study, the patients were divided into 2 groups according to their medial PTS (\u22645.6\u00b0 vs &gt;5.6\u00b0) and lateral PTS (\u22643.8\u00b0 vs &gt;3.8\u00b0), respectively. Clinical outcomes (clinical scores, stability tests and failure rate) were compared between the groups at the last follow\u2010up. Furthermore, survival analysis was performed using the Kaplan\u2013Meier method.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      All clinical scores (International Knee Documentation Committee subjective, Lysholm, and Tegner activity scores) and stability tests (physical examinations and side\u2010to\u2010side difference in Telos stress radiographs) were insignificantly different between the 2\u00a0groups classified based on medial or lateral PTS. However, the failure rate was significantly higher in patients with medial PTS &gt;5.6\u00b0 (16.1% vs 5.1%,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .01) or lateral PTS &gt;3.8\u00b0 (14.5% vs 4.7%;\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .01).
